Consider - an app that replicates this functionality on the phone, but tracks if the user at any point closes the app. This then is reported to the teacher so the teacher knows if there was any cheating.
I love how the first answer that HN proposes to a social problem is 'more capitalism'.
Why not... Just not use graphing calculators in high schools? What's wrong with pencil and graph paper? Not a single one of my algebra or calculus courses ever used the TI-83 for anything that I couldn't do by hand, or with an $8 calculator.
There is zero reason for why high school test questions should ever require a smartphone, app, calculator, or any other electronic device.
More capitalism (or better to say market) is always good answer because it helps to solve situations where people are stuck with inefficient and useless products. If children and parents could choose between schools with different programs, and teaching apps, this expensive and outdated calculator would not exist now.
Scientists don't use apps on computers or smartphones.
Scientists use Jupyter and Matlab. For high school courses, you could even get away with something like Excel or Sheets, or LibreCalc.

The best product in this case, is no product.

This is the last thing on people's minds when choosing schools.
